CHAPTER 15 Filters 15.1 Overview This chapter introduces three types of filters supported by the ZyXEL Device. You can configure rules to restrict traffic by IP addresses, MAC addresses, application types and/or URLs. 15.1.1 What You Can Do in the Filter Screens • Use the IP/MAC Filter screen (Section 15.2 on page 110) to create IP/MAC filter rules. • Use the Application Filter screen (Section 15.3 on page 112) to allow or deny traffic from certain types of applications. • Use the URL Filter screen (Section 15.4 on page 113) to block access to web sites. 15.1.2 What You Need to Know About Filtering IP/MAC Filter Structure An IP/MAC filter set consists of one or more filter rules. The ZyXEL Device allows you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system. URL The URL (Uniform Resource Locator) identifies and helps locates resources on a network. On the Internet the URL is the web address that you type in the address bar of your Internet browser, for example "http://www.zyxel.com". P-660R-Tx v3s User's Guide 109
